SPECIFICATION forming part of Letters Patent No. 767,373, dated August 16, 1904. Application filed March Z4, 1904. Serial No. 199,680. (No model.)

To f1.7] An/'tom/ it puny concern:

Beit known that l, JOHN E. BERRY, a citizen of the United States, residing at Monongahela, in the county of I/Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Glass-Furnaces;

and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the figures oi' reference marked thereon, which form a part of this speciiication.

The object or' my invention is an improved form of glass-melting furnace to be operated in conjunction with a blowing device used in the manufacture of plate, window, or cathedral glass.

In the accompanying' drawings, in two sheets, forming a part Yof this speciiication, I have illustrated my invention by several views, in which- Figure 1 is a longitudinal section of the furnace. Fig. 2 is a top sectional plan view of the same, taken on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal side elevation of my furnace. Fig. 4 is a cross-sectional view of the gathering-chamber and heating device, taken on the line 4 4 of Fig. 2. Fig. 5 is a crosssectional view of the channel-passage and heating device, taken on the line 5 5 of Fig. 2. Fig. 6 is a sectional View of one ot' the blocks used around the gathering-chamber, taken on the line 6 6 of Fig. 7. Fig. 7 is a face view or' the same. Fig. 8 is a side View of a series of blocks forming the walls surrounding the channel-passage. Fig. 9 is a sectional View of one oi' the blocks used in forming the walls surrounding the channel-passage, taken on the line 9 9 of Fig. 8.

In the drawings numerals of reference designate like parts throughout the several views.

The numeral 1 is an ordinarily-constructed furnace having the tank or melting-chamber 2 and working openings 8 and 3 therein.

4 is a stopper at the inner end of the channel 6 and adjustable through the opening 3. Leading at right angles from the meltingfurnace is a heating-chamber 5, in the center or' which is a channel or inclosed passage 6,

through which the melted glass from the furnace is carried to the gathering or drawing chamber V7, located at the farther end of the channel 6.

5' represents the outer walls of the chamber 5.

8 8 are two combustion-chambers` one above the other, formed by the blocks surrounding the gathering-chamber 7..

9 9 are gas-burners introduced through the blocks forming the outer walls of the chainbers 5 and 8 8, a single series oi' burners being used at the side of the chamber 5 and so placed as to play direct against the sides ot' the channel 6, while a double series or' burners are employed at the wider end surrounding the gathering-chamber 7, as seen in Fig. 3.

9 is a pipe supplying the burners with gas. Communication is had with the combustionchambers 5 and 8 8 to the draft-stack 10, located near the melting-chamber.

11 represents one of the clay-block sections used in forming the heating-chambers surare openings therein for the introduction ot' the gas-burners 9.

13 is one of the clay-block sections used in forming the walls of the heating-chamber 5, having an opening 14 therein for the introduction or' the burner 9.

The glass being thoroughly melted in the chamber 2, the stopper 4 is removed through the opening 3, when the molten glass will iiow through the channel 6 into the gathering or drawing chamber 7 and will be kept in a heated or workable state by heat generated in 'the chambers 5 and 8 8 from gas introduced therein.

The walls of my furnace, including those surrounding the channel-way 6 and gatheringchamber 7 will be made of the usual refractory material.

Having thus `fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a glass-furnace, a melting-chamber, a central way or channel leading from said chamber, a drawing-chamber formed at one end of said channel-way, a heating-chamber surrounding the channel, double heating-cham-v rounding the gathering-chamber 7. 12 12 IOO hers surrou ndin g the d rmving-ehamber,means extending through the walls ot' the Said double chambers and henting-ehfunber for introducing gas thereto, yund :L communicating 'flue formed near the melting-Chamber, Substantially as Set forth.

2. In a glass-furnace, the Combination with a melting-chamber of the channel-way 6 Coinniunicnting with :L gathering or drawing ehzunher 7 formed et the 'far end thereof; the heating-chamber 5 formed in hloek-sectionS surrounding the channel 6; the double heating- Chambers Vformed in the block-sections Surrounding the gathering or drawing chamber 7, ineens or' introducing gas to the Chambers I 5 5 und 8 8 through the block-sections and a eonununieating Hue l() formed near the furnace proper; Substantially as described :1nd Shown.

In testimony whereof I affix my Signature in 2O presence ot' two witnesses.

JOHN E. BERRY.
